[2.2] Problems with grid to grid drag and drop (even on official examples)

Hello out there,

I have found two bigger problems with the drag and drop-ability using two grids. The problem I found appears also on the official example. When you use the horizontal scrollbar, the drag and drop ability disappears on the grid rows. It seems like that there is an invisible mask that listens to the drag and drop, and this mask scrolls away.

The other problem is, that on this mask the mousedown-event drops into a black hole, but on the part where drag and drop does not work, the event is correctly fired. The "black-hole"-effect for (only) onmousedown is even there if you attach the event to the whole document.

That only accounts for being able to drop when a grid has been scrolled.

No, I cannot drag one or multiple rows if I try to grab them from a position where I have scrolled to. On wide tables, this is a serious problem because you have to scroll back to the left. The problem occurs on the official sample as well.

I have this exact same problem. I was having other problems related to horizontal scrolling. Condor posted a fix for those. I always thought this DnD bug was a result of those other bugs. I'm still unable to drag n drop rows after horizontal scrolling though....
